Focus Forge Motorsport Blow Off Valve Valve. Direct fit replacement for OEM valve to suit Focus RS and XR5.
Made from billet polished aluminium, this valve dumps the charge-air to the inlet pipes. This increases both quicker throttle response and higher clamping load to maintain boost pressure more reliably. Mounted on the turbocharger.
Comes with a selection of springs to perfectly set the blow off point to match your engine mods.
Suits Focus RS and XR5
